Answer 1

Most of the cells in your body require oxygen delivery from your heart, so once your heart stops beating they won’t last long.

There are, however, lots of bacteria in your digestive system. They’re not technically human, but they do make up part of your body, and those can survive for a very long time after you’ve died.
